In this paper, we have presented a photonic crystal sensor including nano-grapheme layers under the Kretschmann configuration. The band structures, surface modes, reflectivity and sensitivity of photonic crystal sensor in different chemical potentials are calculated by transfer matrix method. Our results show that with increasing the chemical potential, the width of zero-gap in the band structure of photonic crystal expands and surface modes shift to higher frequencies in both conventional band gap and zero-gap. Our investigations illustrate that the figure of merits of the proposed biosensor for the surface mode of zero-gap in  µc= 0.2eV and for that of Bragg gap in µc= 0.4eV are considerably higher compared to the figure of merits in other chemical potentials presented in our study.
